.-. `aolims. e (o1. 454-77) V'This invention relates `vto` improvements,fin drawer constructions'and particularly to the supticles, whichdevices are commonly known in the trade as drawer slides. TheVinventionv may be considered as an improvement over the constructiondisclosed in'my prior United `States vLetters Patent'No. 1,344,845,issued February 9, 1932.

An object of the present-invention is to provide an improved drawerslideconsisting of a'rail, a

slide slidable thereon, which intu'rn slidably sup-l ports a drawer,tray, or similar-article.

`Specifically the inventionhas ast one of its objects the provision ofsuitable bumpers or devices formed of relatively soft material adapted`to vengage to limit sliding movement ofthe slideirela'- tively tothe-rail and to limit sliding vmovement of the drawer relatively 'to theslide. These bumpers orl devices formed of soft material on engagementare relatively noiselelssso that when parts ofthe constructionreachthelimits'of their movement no undesirable .noise is produced thereby. le .y

Another object of the -invention is" to provide aniimproved drawer slideconstruction having a rail and a'slide, the rail andslidebeing of suchdesign as to be capable of easy manufacture andv .f

installation, at the same time being relatively sturdy to form a solid,supportxfor'a. heavily loaded vdrawer or" tray. Y

Another object of the invention is to provide ar drawer slideconstruction having a railv and a slide with a drawer slidable j ontheslide,theconstruction being such as to enable the'drawerjto assume atilted position with respect to the'slide. Such a `construction isfrequentlyfound highly desirable in 4les and various other cabinets.

`Another object of the inventionv is to provide a suitable form of slideconstruction whichjcan be advantageously employed in ,conjunction withgrates or trays conventionally' employed in re-` frigerators and likeconstructions, enablingy the grate or trayv to be completelyjwithdrawnfrom the refrigerator, supportedin yhorizontal ,positionV f by theslide, and caused to slide into the refrigerator when'desired..

With theforegoing andother objects in View, which will be made 4manifestin the following de#- tailed description, andspe'cioally pointed out inithe appended claims,reference` is had to theac-`` companying drawingsforanyillustrative embodiment of the invention, wherein:

I have illustrated the twodrawers in Figure 1 asbeirig separatedby adivision strip 45 but the use of this division"'strip is notnecessaryanclmayv4 be completely* omitted, in which event each drawer'issupported solelyby its rails'and slides on lthe 'side-walls vII of thedrawer receivingv chamber. The ,top'offront `wall 4 2 of the lowerdraweris. preferably so arranged as to fitl snugly 'of the front wall 42of 'the .up-.L

Figur'e. The. slides 52 are of substantially the same constructionillustrated in Figure l'with'the exception that at the forward endsofthese slides' instead of having clip 38and Vrubber'lolock 39 it.ismerely `an',.upstanding lug 1,53, fseef Figure '7,

whichis" integral'with the bottom or horizontal portion yof theslide;The drawer employed has sides 54, afrontmwallf55, abottoml 53 disposedabove the b'ottom.of the sides 54 and"fron`t wall ,55, and a rear wall51. Rear wall 5l isdisposed ferirefglyef the reeredsef heiem 56, were@zoy frontali portions p `andhorizontal-portions of the rails, the`vertical rear ends'l or sides'll arerounded, as'in'dicated at;Stopblocks'S arefastenedto the bottom 55' near the side walls llandare-adaptedto enlgage `lug 53.

In` this construction when! the drawer is withdrawn into substantiallyfully with-V drawn position it is possible to tilt thedrfawer into 'theposition' shown. On swinging the drawerxback into horizontal position itmay be vcaused to slide into drawer receiving chamber 58; rst sliding onthe vslide and then causing slide 2 to sliderearwardly on 'rail' 5i.y Y

vInthe modification shown in Figure Bthere is illustrated arefrigerator, the interior'oflwhich constitutes .a 'tr'ayireceivingchamber G. Rails 5i are secured to the sides of chamber G0, these railsbeing of the same construction previously f described in conjunctionwith Figure 3. The slides 82 are of substantially the same constructionas disclosed in Figure 4 except that the rubber block 3S and clip 38 areomitted and in place thereof a pin 63 projectsinwardly from the verticalportion of the slide.` The grate or tray is indicated at 64% and hasrods 65' secured thereto which are bent downwardly, forwardly and thenupwardly, providing runners 56. Runners G6 are connected to the body ofthetray by suitable struts or posts 6l and the rear ends of the runnersare bent upwardly behind the pins 63. In

this construction it is possible to slide the tray on its runnersforwardly, sliding movement taking place on the slides G2 until the pins`63 are engaged by the upwardly bent ends at the rear ends causes theslides t2 to 'be carried rearwardly by the tray and to slide rearwardlyon rails 6 i.

In all modifications the hooks 2l -on the rails hold the slides inhorizontal position so that althoughv considerable weight is placed onthe forward ends of the slides they cannot tiltrelatively to the rails.l j

From the above described constructions it will be appreciated that animproved drawer slide construction is provided having severaladvantageous improvements incorporated therein rendering the slidevirtually frictionless in operation and virtually noiseless. that boththe rail and the slide can be constructed each of a single piece ofmetal and the bumpers and 21 and the block 39 which are formed of softermaterial applied thereto.

Various changes may be made in the details of construction withoutdepartingfrom the spirit or scope of the invention as defined by theappended claims. y
